Improvement in hose-coupling

Leners Patent No. 92,954,'dad July 27, 1869- The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, J OHN H. GEORGE, oiNewark,

in the county of Essex, and State of New Jersey, have invented an Improved Hose-Coupling for portable drop-ligh ts; and I do hereby declare that the following lis a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in the inode employed in securing the rubber pipe in the coupling.

In the ordinary coupling, the rubber is screwed into the end of it, Aand is held in .place bythe thread ofthe screw only. This mode of attaching' the hose or pipe is very defective, as the tube is very liable to come ont in use, or get loose, so that the gas may escape.

To provide against these defects is the object of this invention.

I construct a small metal tube, O, with one end tapering, and a liange, E, across the other end, filling the space in the female section of the coupling B. This, when in its position, the end passing into the rubber tube A, is pressed `down by the male section j of the coupling D being screwed down into the couplingr B. This crowds the rubber closelyinto the thread of the screw, and over the shoulder above the saine, holding it positive, and allowing no chalice for it to become loose, or be detached.

This becomes at once a simple and positive hosecoupling, and not liable to get outof repair.

The mode of constructing the hose-coupling with male and female sections, 1s also believed to be new.

Therefore, Y

What I claim as my invention, and desire to secure by Letters Patent, is

1. The hose-coupling, constructed with thc male 'and female sections B, substantially as and for the.

purpose specified.

2. The tubeG, or its equivalent, in combination with, the coupling B D, substantially as and for the ur ose s ecified. p p p J. H. GEORGE.

Withesses.
